Title: Cavitation errosion reduction device for hydraulic machine
Inventor: OKAMURA TOMOYOSHI
IPC: F03B11/04
Filed: 1985-04-10
Abstract: PURPOSE:To stabilize the flow of a liquid and lessen the occurrence of cavitation errosion by providing a plurality of fins in the same direction of a main liquid flow at a position possibly exposed to cavitation errosion in the flow passage of a hydraulic machine. CONSTITUTION:It is assumed that the negative pressure side 1a1 of a vane 1a (1b and the like) is exposed to cavitation 3 propagating from the leading edge 1a3 and terminating at the halfway 3a of the length of a plurality of fins 2, which is provided extending from hub side to shroud side at intervals approximately equivalent to about a half of the thickness of the vane at the negative pressure side 1a1. Near the termination point of the cavitation 3, an infinite number of bubbles is formed and collapses. On the other hand, the fins 2 toward the same direction as a main liquid flow are provided in the vicinity of the collapsing area. Therefore, a liquid flow accompanied by an infinite number of bubbles is well guided by the fins 2 and well adjusted for smooths flowing downwards. Consequently, the instability of cavitation collapsing is reduced and the generation of cavitation errosion can be lessened, thereby improving the reliability of a hydraulic machine.

Title: Pressure sensor
Inventor: SHIMADA SATOSHI
IPC: G01L9/04
Filed: 1981-05-20
Abstract: PURPOSE:To improve precision, by a method wherein a difference in expansion between a diaphragm and a securing stand is absorbed by a recess part formed in a connection of the two parts, and this prevents the procution of a change in a zero point and in sensitivity due to a temperature change. CONSTITUTION:A recess 12, having a V-section, is formed in a connecting surface where a thick securing part 6, forming a periphery of a thin pressure- sensitive part 3, is positioned facing and opposite to a securing stand 6, whereby a difference in expansion between the diaphragm 1 and the securing stand 6 is absorbed by said part, and even if a surrounding temperature changes, resistance change of a strain gauge 9 is constant to prevent the product on of a change in sensitivity. In a condition that a pressure is applied, the unbalanced voltage of the bridge of the strain gauge 9 does not change as well, and as a result, a change in zero point is prevented from occurring. Finally, a resistance value of only the strain gauge 9 changes by the same amount by the temperature factor, but a bridge consists of the 4 or 2 strain gauges 9. This prevents the production of a change in the unblanaced voltage or the output voltage.

Filed: 1986-04-02
Abstract: PURPOSE:To restrain higher order vibrations of a wire and enable high-speed printing, by providing a magnetic circuit comprising a leaf spring part and an armature, the wire joined to the armature, and a restraining plate located at such a position as to make contact with the armature immediately after printing. CONSTITUTION:With a coil 3 energized, an armature 6 is released from a yoke 2, and immediately after the tip of a wire 9 reaches a printing medium 12, a central part of the armature 6 is displaced toward the tip of the wire 9 although a tip part of the armature 6 is restricted by the wire 9 in being displaced in an advancing direction of the wire. However, since the central part of the armature 6 is located in extreme proximity to a restraining plate, higher order vibrational displacements of the central part are restrained while they are slight. After the energization is stopped, the armature 6 is rapidly returned by an attractive force of a permanent magnet 4 which is recovered, whereby a series of printing operation is completed, and superimposed higher order vibrational components become faint.
